The advancing monsoon is a seasonal change in the direction of the prevailing winds of a region, which brings rainfall to India and Southeast Asia. It occurs in the middle of the summer season, typically from June to September. The following are some features of the advancing monsoon:

• Wind direction: The wind movement is from sea to land, and the wind blows from southwest to northeast.
• Rainfall: The advancing monsoon brings the maximum amount of rainfall in India, with the northeast part of India receiving the most rainfall.
• Wind moisture: The advancing monsoon carries moist winds.
• Duration: The period of the advancing monsoon starts in June and ends in September.

When the advancing monsoon hits India, it first brings rainfall to the Malabar coast of Kerala and then moves towards the Konkan coast. The Western Ghats receive heavy rainfall at the beginning of the monsoon. The retreating monsoon occurs from October to November and is characterized by the movement of wind from land to sea. The maximum amount of rainfall due to the retreating monsoon takes place in the coast of Tamil Nadu.
